My 1yr old threw up last night and today complained his tummy hurt. Is there such a thing as a 1 day viral stomach flu?

In brief:
Yes

Norovirus and other viruses can have a very short course.

However, don't be surprised if it's not quite over yet. It may be, or he might develop diarrhea. For diarrhea or tummy pain, try bland foods such as the brat diet (bannas, rice, applesauce, toast) if he is agreeable to them.
